COMBINED SELF-FEEDING BE NCH-DRILL AND LATHE.

SPECIFICATION forming part of Letters Patent No. 559,003, dated April28, 1896.

Application filed May 17, 1895. Serial No. 549,626. (No model.)

T0 aZZ whom it may concern:

Be it known that I, JAMES B. TAYLOR, a citizen of the United States,residing at Fairview, in the county of Sierra and Territory of NewMexico, have invented a new and useful Combined Self-Feeding Bench-Drilland Lathe,of which the followingis a specification. The object of myinvention is to produce a neat, cheap, portable, and efficient drill foruse by gunsmiths, watchmakers, &c., one which can be readily and firmlyattached to a bench or table, and which will automatically feed the workto a drill, and which can also be quickly adapted for use as a lathe.

A further object of my invention is to reduce the friction to a minimumand prevent any cramping of the traveling upright which carries the workup to the drill.

Another object of my invention is to provide means wherebythecylindrical guides, which guide the traveling upright, will bear evenlyand thereby prevent any variation or jumping of the work while beingcarried onto the drill by the upright traveler.

Another object of my invention isito provide a self-feeding drill with aclamping device which will advance upon the drill in the same plane, andat the same time so arrange the parts that the drill and advancingclamping device will be free from obstruction, will be easy of access,and will have sufficient clearance for ordinary work.

My invention also comprises the various features of construction andcombinations of parts hereinafter fully set forth and claimed.

The accompanying drawings illustrate my invention.

Figure 1 is a side elevation of my improved device. Fig. 2 is asectional view on line 2 2, Fig. 1, looking toward the right. Fig. 3 isan enlarged fragmental view showing my improved chuck-holding vise. Fig.4 is a view of one of the jaw-blocks removed from the upright.

I11 the drawings, A represents abed-plate, which is provided with twoclamps B B, mounted at right angles to each other, so that one clampwill clamp upon the edge and the other clamp will clamp upon the end ofthe table or bench. By this arrangement the clamps hold the drill morerigidly in place than is possible when the clamps are arranged parallelwith each other.

C 0 represent two uprights of the drillframe. These uprights arearranged at one end of the bed-plate A and project upward therefrom andserve as a support, in which is journaled one end of each of therotating guide-shaftsD D, and also one end of the screw feed-shaft E.The other ends of such shafts are journaled in a single upright F, whichis arranged at the other end of the bed plate.

Upon the guide-shaft E is secured a driving-pinion d. This pinion mesheswith an upon the guide-shaft D. A drill-shaft G is journaled in theframe above the gear-wheel cl and is provided with a pinion g, which isarranged to mesh with the gear-wheel d. This shaft is providedwith achuck G and with a band-wheel g, arranged upon the outside of the frameof the drill-frame.

,of a vise-screw J to grip the material to be drilled and to hold itrigidly in position in front of the drill G. The upper part of thisupright I, which supports the vise, is provided with a rectangularopening K, within which two blocks 7c of hardened steel are arranged.The ends of these blocks are grooved and slide along rods K, which areinserted through the upright after the blocks are placed in position inthe opening. Two vise-screws L L are screwed through the upright andattached, respectively,to the blocks is and 7c,so that such blocks maybe forced together to grip a chuck or any object to be drilled and maybe shifted from one side of the rectangular opening to the other, ifdesired. This allows the article which is gripped by the jaws to beshifted so that that part of the article into which it is intermediategear-Wheel cl, which is secured desired todrill the hole may be broughtdirectly in front of the drill. This also enables me to use my machinefor drilling holes in the ends of shafts or rods, and such holes may bebored either centrally or eccentric to the center of such shaft, asdesired. D is a crank by which the mechanism is operated.

The pinion cl is detachably secured to the shaft D by means of aset-screw 2, so that when it is desired to use the device as a lathesuch pinion may be detached from the shaft D and by rotating the shaftEand by means of the crank e the upright I may be carried backward andforward to suit the work to be turned.

A center-chuck (not shown); is fixed between the jaws 7a 7a and asuitable lathe-chuck is fixed in the chuck G. Then the pinion g is freedfrom its engagement with the shaft G and a band (not shown) is passedover the pulley-wheel g, whereby the work is ro-- tated. ranged tosupport the cutting-tool. However, these are minor matters in which anyone versedin the art is familiar and therefore it is not necessary thatI- should makea detailed description of such matters herein.

By means of the crank e the screw-shaft E maybe rotated tocarry thesupport I nearer to or farther from the chuck G tosuit the article to beturned upon the lathe.

By arranging thetravelingupright I upon the guide-shafts D D and bycausing such guide-sl'iafts to rotate as the upright travels therealongto carry the work against the drill practically all friction is avoided,and the guides constantly present a new face to receive the pressurewhich must be borne th ereby and prevent the traveling upright fromcramping upon the two guides D and D, and y this means the device isadapted to be used 1 they are therebycauscd to wear evenly.

Any suitable support may be a-rfor an indefinite period without becomingworn to-such an extent as to impair'its effectiveness.

Now,'having described my invention, what I claim as new, and desire tosecure by Letters A Patent, is- 1. The combination set forth of theguideshafts; the feed-shaft the upright arranged to be operated by thefeed-shaft and to travel along the guide-shafts, and provided at itsupper end with the rectangular opening; the jaw-blocks groovedat eachendand arranged in the opening in the upright; the rods inserted throughopenings provided in the up.- right, seated in the grooves in suchblocks vise-screws, one screwed through each side of jsaid upright andsecured to one of the jaw- ;blocks; the drill-chuck; means for rotatingthe chuck and meansfor operating the feedishaft. I

2. In a drilling-machine, the combination f the frame; the driving-shaftjournaled in the frame and provided with the driving-pin- ,ion; thedrill-shaft journaled in the frame land provided with the driven pinion;the intermediate gear-wheel meshing with the driving-pinion and with thedriven pinion; two parallel guiding-shafts secured tovthe frame;screw-threaded.feed-shaft provided with a gear-wheel, and journaled inthe frame pari allel with the guiding-shafts; a traveling caririerarranged to be carried back and forth Eupon the guiding-shafts by theaction of the ifeed-shaft; and a pinion connected with the iintermediatcgear-wheel and meshing with 1e gear-wheel upon the feed-shaft.
